525L

Explanation:

Given parameters:

Volume to Temperature ratio = 1.75

Temperature = 300k

Unknown:

Volume of the gas = ?

Solution:

We must carefully analyze and comprehend the detailed description of this experiment:

 It was suggest that the gas could expand or shrink without changing the pressure of the gas inside.

This implies that the pressure in the vessel is constant

This similar to the postulate of the Charles's law: The volume of a fixed mass of gas is directly proportional to the absolute temperature if the pressure is constant.

 Mathematically;

                 \frac{V1}{T1}  = \frac{V2}{T2}

V and T are the volume and temperature

 Now we can solve the given problem;

           \frac{V}{T}  = 1.75

Since temperature is given as 300K

 Input the variables:

           \frac{V}{300}  =  1.75

          V = 1.75 x 300 = 525L

In Boston elevation 20 feet, your mass is 75 kg. On top of Mt. Everestt (elevation 29,029 feet) you mass would be
Tpy6a [65]

Answer:

75 kg or 75,000 g

Explanation:

Mass is a measurement that describes the amount of matter within an object. This is a constant measurement that does not change regardless of the object's location.

As such, a person's mass would be the same at both elevations.

**Their weight, however, may change.

** 1 kg = 1,000 g
